An article published in the May/June 2018 issue of The Military Engineer (TME) discusses the multidisciplinary effort that HydroGeoLogic, Inc. (HGL) used to remediate and achieve regulatory compliance and closure for Groundwater Operable Unit 1 (OU-1) at the former Fort Ord National Priorities List (NPL) site in Marina, California. From 2003 through 2017, HGL worked with the U.S. Army Corps of Engineers under multiple contracts to address groundwater contaminated with chlorinated solvents and the emerging contaminants perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Notably, the American Academy of Environmental Engineers & Scientists® recognized this challenging and complex project as a Grand Prize Winner in its 2017 Excellence in Environmental Engineering and Science™ competition.
The article addresses the following key elements underlying HGL’s mission success:
- Using performance-based remediation (PBR) and fixed-price contracting vehicles;
- Applying an integrated approach to address site biological, hydrological, and engineering factors;
- Using groundwater flow and contaminant transport modeling; and
- Achieving response complete and site closeout using innovative optimization approaches.
